Ancient groundwater system on Mars, not current.
- misterprime 8y agoWell that's a big difference.
- mirimir 8y agoYeah, like billions of years. But hey, maybe there's still lots of ice, here and there.
- InclinedPlane 8y agoNo maybe about it, there is lots of ice. There may also be lots of sub-surface groundwater, we just don't have solid evidence of that yet.
